The tight design with an inner diameter of 6.03mm can improve initial velocity. In order to maintain its accuracy, we have selected materials with the necessary strength without compromise, and we have also omitted unnecessary coatings, creating an inner barrel that satisfies all the elements necessary for hitting the target with BB bullets.
